Photoshop is tremendously complex and nuanced, and there are always techniques or entirely new features to be discovered. This helpful video will give you five lesser known tricks to add to your arsenal.
Coming to you from Jesús Ramirez of the Photoshop Training Channel, this video outlines five highly useful techniques and features in Photoshop. Perhaps my two favorite tips are working with luminosity masks and making selections with color ranges. As you probably already know, a lot of work in Photoshop revolves around making targeted adjustments, and so, having a multitude of ways to select certain parts of your image is important to being able to work efficiently and precisely. Very often, you'll want to add an adjustment to a certain range of luminance values or address a certain set of colors, which is where these tricks become so enormously handy. An additional tip: when working with the Color Range selection tool, if you're working with something like skin, try changing the sample size from "point" to something like "11 x 11 average." Doing so will help ensure you don't end up with an erroneous selection if you accidentally click a pore or the like and will likely give you a result that's more in line with the general tone.
